Title: Vertical magnetic recorder
Inventor: FUJINO KENJI
IPC: G11B17/04
Filed: 1983-06-22
Abstract: PURPOSE:To control freely the contact between a vertical recording medium and a head and to assure the record/reproduction with high efficiency without causing any damage to the recording medium and the head, by using the attraction power of a U-shaped electromagnet to allow the recording medium to come near to or bring it into contact with a main magnetic pole. CONSTITUTION:The magnetic pole ends 61 and 62 of a U-shaped electromagnet 6 are set close to each other on the surface of a vertically magnetized film 13 of a recording medium 1. This magnet 6 contains a U-shaped magnetic matter 7 and an energizing coil 8 which is wound round the matter 7. The attraction force F is equal to the square product of the sectional area S and the magnetic flux density B. If the area S is set much larger than the sectional area of a main magnetic pole 4, the attraction force of a desired level is obtained. At the same time, the density B can be reduced down to such a level that can be neglected in comparison with the density of magnetic flux. Furthermore, the characteristics of magnetization of a vertically magnetized film 13 has hysteresis, therefore the recording using the residual magnetization is impossible unless the magnetic flux density higher than a certain level is applied. Therefore, the contents of the medium 1 are not rewritten by mistake as long as the density B is kept under said level.

IPC: G11B7/26
Filed: 1995-04-14
Abstract: PURPOSE: To obtain a process for producing an electroforming mold which allows defectless peeling of a motor stamper and the electroforming mold. CONSTITUTION: The electroforming mold duplicating the mother stamper is produced by forming a nickel electroforming film on the front surface of the mother stamper 12 having a first nickel sputtered film (I) 3 on the front surface formed with rugged patterns, then peeling the nickel electroforming film.

Abstract: PURPOSE:To dispense with opening-closing of a cover of a light emitting part by an operator with every analytical process, reduce labor in analysis, and shorten analytical time by automatically setting rotation of a sample with every analytical process. CONSTITUTION:A shaft 10a of a rotary means 10 is extended, and a rack 11 is moved, and clutch mechanisms 12a and 12b are rotated according to rotation of a gear 13, and a central shaft 14 is rotated.

Thereby, the pushing body 21 downward pushes the upper end of a gripping-holding claw 23, and the tip 23a of the gripping-holding claw 23 releases a grip-hold of the sample 25 by being separated from the sample 25 against energizing force of a spring 24. As a result, a flange 25a of the sample 25 is situated at the opening 26. Next, a shaft 27a of a cylinder 27 is lowered, and a pushing member 28 presses the flange 25a of the sample 25 to the opening 26 of the light emitting part. Thereby, the flange 25a is fixed in close contact to the opening 26 of the light emitting part, and prescribed processing is performed.

Title: Method for preventing groove corrosion in weld zone of electric welded steel pipe
Inventor: KURISU TAKAO
IPC: B23K11/34
Filed: 1983-06-23
Abstract: PURPOSE:To prevent deterioration in the weld zone of an electric welded steel pipe owing to the accumulation of the nonmetallic inclusions in said zone and to prevent groove corrosion in welding of said pipe by plating one side end or both side ends of a blank material for the pipe with >=1 kind among elements which are resistant to groove corrosion and have a specific thickness then subjecting the material to resistance welding. CONSTITUTION:One side end face or both side end faces of a blank material to be welded for an electric welded steel pipe are plated with >=1 kinds among elements which are resistant to groove corrosion and have about 0.01-100mu thickness, i.e., copper, nickel, chromium, cobalt, tin, etc. to prevent deterioration in strength. The material is subjected to electric resistance welding via such plating layer. The selective corrosiveness in the weld zone owing to the accumulation of the nonmetallic inclusions such as MnS or Mn-O-S is prevented by the corrosion resistance of such elements, by which the groove corrosion in the weld zone is prevented.

Title: Automatic frequency control circuit
Inventor: MINEMATSU TORU
IPC: H04B1/26
Filed: 1992-05-06
Abstract: PURPOSE:To keep an intermediate frequency signal to an object frequency with high accuracy. CONSTITUTION:A reference frequency signal from an oscillator 15 is fed to a comparator 17 via a frequency divider 16. The intermediate frequency signal from an amplifier 8 is fed to the comparator 17 via a frequency divider 18. Frequency division numbers of the frequency dividers 16, 18 are set to be fr/fc and fg/fc, where fg is an object frequency, fr is a reference frequency of a reference oscillator 15, and fc is a comparison frequency of the comparator 17. The result of comparison from the comparator 17 is fed to a microcomputer 6 and a deviation between the frequency of the intermediate frequency signal and the object frequency fg requested by a demodulator 9 is discriminated to revise a tuning voltage Vc thereby controlling the intermediate frequency signal to be the object frequency fg. When the demodulator 9 starts demodulation at first after tuning to a prescribed channel, a prescribed offset is added/ subtracted to/from a local oscillating frequency and the frequency division number is controlled so that output phases of the frequency dividers 16, 18 are coincident with each other to correct the deviation of a recognized frequency of the phase comparator 17 due to a noise component thereby avoiding mis-recognition of the object frequency fg.

Abstract: PURPOSE:To maintain a superior optical performance without influence due to environmental temperature and humidity by preventing two optical element plates from being separated. CONSTITUTION:A magnetic body dispersing layer 32 into which transparent magnetic fine powder is kneaded is formed on one surface of one optical element plate 1 and N and S poles are alternately and continuously magnetized to form a multipolar surface.

Title: Vertical pnp transistor
Inventor: TABATA TERUO
IPC: H01L27/08
Filed: 1986-05-19
Abstract: PURPOSE:To improve the integration of a vertical PNP transistor by diffusing a separating region until arriving at the surface of an epitaxial layer upward from the surface of a substrate to shorten a separating distance between the separating region and a collector-leading region. CONSTITUTION:A separating region 24 and a collector buried layer 25 formed by so diffusing as to arrive at an epitaxial layer 22 upward from a substrate 21 and an N-type base region 26 formed on a region corresponding to a collector buried layer 25 on the layer 22 are provided. Since the region 24 is so formed as to arrive at the layer 22 upward from the substrate 21, the lateral diffusion of the region 24 on the layer 22 is extremely small, and hence the occupying area of the layer 2 of the region 24 is slightly larger than the area of a diffusion window. Thus, the integration can be largely improved.
